What PDT Partners LLC changed, 2013 to 2026
53 quarterly 13F filings, from Q2 2013 to Q2 2026, each read from the filing itself. A quarter is compared only with the quarter before it, so a quarter with no filing is a gap in the record, not a sale.

The books most like this one
Among the managers whose filings are on file, at Q2 2026. Overlap is the share of the two books that is the same: for every stock both list, the smaller of its two weights, added up. Two books can overlap because both own the largest companies; it says nothing about whether the managers agree.
| Manager | Overlap | Stocks in both | Overlap over time | |
|---|---|---|---|---|
| Quantbot Technologies LP | at least 16% | 128 | Compare | |
| Voloridge Investment Management LLC | at least 15% | 104 | Compare | |
| AQR Capital Management LLC | at least 13% | 108 | Compare | |

“At least” where either manager has more positions than are read each quarter: a stock both hold below that range is not counted.
The filings behind it
Every quarter above is one 13F holdings report, with any amendment the filer made to it applied in the order it was filed. Where the reporting entity changed, each quarter keeps the filer that actually reported it.

Reading this record
A 13F lists US-listed long equity and options at the quarter end, filed up to 45 days later. It shows what was held, not when it was bought or at what price, and nothing short. Where a quarter lists only the largest positions, a name missing from it may still be held below that range; the counts of what was opened and sold always cover the whole filing.
